Thanks to Apoorv Sharma @apoorv-sharma, hnswlib now supports true element updates (the interface remained the same, but when you the performance/memory should not degrade as you update the element embeddings).

Thanks to Dmitry @2ooom, hnswlib got a boost in performance for vector dimensions that are not multiple of 4.

Bugfixes and other updates (@xiejianqiao, @Shujian2015, @mohamed-ali, @hussamaa).

Many thanks to all contributors!
